Despite its reliability, any car, including Nissan Terrano, may encounter a situation where electrical equipment suddenly stops working. In most cases, the problem lies not in a serious wiring breakdown, but in a banal fuse blown. Knowing where it is fuse box and how to properly service it will allow you to quickly restore the functionality of your headlights, power windows or cigarette lighter without contacting a service center.
Owners Nissan Terrano It is important to understand that the car has two main places for placing electrical circuit protection elements: one unit is located in the engine compartment, and the second is located directly in the passenger compartment. Each of them is responsible for its own groups of current consumers, and incorrect diagnosis can lead to loss of time or even damage to the electronics.
In this article we will analyze in detail the location of the nodes and provide current fuse diagrams and give step-by-step instructions for checking and replacing them. We'll also look at common problems and give tips on how to avoid power problems in the future.
Proper diagnosis begins with understanding your vehicle's electrical structure. Nissan Terrano is equipped with several blocks, each of which has its own characteristics. Ignoring these nuances often leads to owners looking for a fuse in the wrong place.
Location and purpose of the main protection units
In the car Nissan Terrano The protection system against short circuits and overloads is divided into several zones. Main fuse box in the cabin located under the dashboard, on the driver's side. To access it, you need to open the cover, which is located on the side panel of the dashboard. In some configurations, access may be difficult and you will need to remove the plastic decorative element.
The second important node is fuse box in the engine compartment. It is a sealed black box located on the left side of the engine (when viewed in the direction of travel). This unit is responsible for the operation of high-voltage and power circuits such as the generator, ignition system, cooling fan and fuel pump. This is where the most powerful relays and fuses are located.
It is worth noting that the location may vary slightly depending on the year of manufacture and the market into which the car was released. However, the principle remains the same: the power circuits are protected under the hood, and the comfort and lighting circuits are protected in the cabin. When troubleshooting, always start by checking the unit that is responsible for the failed device.
For ease of maintenance, each block is equipped with a special plug on the inside of the lid, on which is applied fuse diagram. It shows the number, denomination and purpose of each element. If a sticker is worn off or damaged, do not try to guess the purpose by color - this can lead to serious consequences.
Detailed diagram of fuses in the cabin
The indoor unit contains elements responsible for the operation of the audio system, cigarette lighter, power windows and side lights. Typically, fuses with ratings from 5 to 30 amperes are used here. The colors of the fuses are strictly standardized: yellow - 20A, red - 10A, blue - 15A, and so on.
Particular attention should be paid to the cigarette lighter fuse, as it often blows due to the use of low-quality chargers or powerful car refrigerators. In the scheme Nissan Terrano this element is usually denoted as ACC or CIG. If the cigarette lighter stops working, check it first.
Below is a table with the most commonly used fuses in the cabin for typical configurations:
| Designation | Denomination | Purpose |
|---|---|---|
| F1 | 10A | Driver's windows |
| F5 | 15A | Cigarette lighter |
| F12 | 7.5A | Tail lights and lighting |
| F18 | 20A | Audio system |
| F25 | 10A | Interior lighting lamps |
Not all fuses are clearly marked on the body, so always check the inside of the cover. If you see that the fusible insert inside the transparent body is torn or blackened, the element requires immediate replacement.
It is important to understand that replacing a fuse with an element with a higher rating is strictly prohibited. This may cause the wiring to overheat and cause a fire. If the new fuse blows immediately after installation, there is a short circuit in the circuit, and simply replacing it will not solve the problem.
Features of the fuse box under the hood
Engine compartment Nissan Terrano - This is an area of high temperature and vibration, so the protection elements here are made more massively and reliably. Block in the engine compartment Contains fan relay, fuel pump relay and main relay (IGN). Powerful fuse links for 40A, 60A and even 80A are also located here.
This unit is accessed by unsnapping the plastic cover latches. Be careful when opening if the engine is hot. Inside you will find not only fuses, but also relay blocks, which often cause malfunctions. For example, if the cooling fan does not turn on, the problem may be with the relay and not the fuse.
Carefully inspect the contacts on the blocks. Over time, high temperatures can cause them to oxidize or weaken, resulting in poor contact and overheating. Cleaning the contacts and tightening the retainers can solve the problem without replacing expensive components.
Diagnosing circuits under the hood often requires a multimeter, since some fuses are enclosed or located in hard-to-reach places. Use the instrument's probes to check for voltage at the fuse inputs and outputs.
Pay special attention to the ABS and electronic engine control fuse. Failure of these elements can lead to a complete stop of the car or blocking of the brake system. Never attempt to start the engine if the main engine control fuse has blown..

Tools and fuse replacement procedure
The process of replacing the fuse link does not require special skills, but must be performed carefully. All you need is tweezers or a plastic puller, which is often built into the lid of the unit. Using metal tools (screwdrivers, pliers) may short circuit or damage the contacts.
Before starting work, be sure to make sure that the ignition is turned off. Ideally, it is better to disconnect the negative terminal of the battery to eliminate the risk of an accidental short circuit. However, to simply replace the fuse in the passenger compartment, simply turn off the ignition and all current consumers.
Here is a step-by-step algorithm of actions:
- 🔍 Find the blown fuse using the diagram or visual inspection
- ✂️ Remove the element using a plastic clip
- 🔍 Check the integrity of the fuse link inside the housing
- 🔧 Install a new fuse with an identical rating
- ✅ Check the operation of the device after replacement
☑️ Preparing to replace the fuse
If you do not see a clear break in the fuse link, but the device does not work, try replacing the fuse with a known good one. Sometimes the contact inside the housing is broken without visible external damage. In such cases, replacement usually solves the problem.
After installing a new element, be sure to check its operation. If it burns out again, do not try to repeat the procedure multiple times. This is a sign of a serious fault in the circuit that requires professional diagnosis.
What to do if there is no spare fuse?
In an emergency, you can use a fuse from a circuit that is not currently in use (for example, a cigarette lighter, if you do not plan to use it urgently), but only with the same rating. Never use copper wire or a paper clip in place of a fuse!
⚠️ Attention: Never use fuses with a rating higher than that specified in the diagram. This may cause the wiring to melt and cause a fire.
Always keep a selection of fuses of different ratings in your glove compartment. This is standard practice for any car enthusiast, especially if you travel frequently. The set must include elements from 5A to 30A.
Frequent malfunctions and their diagnosis
The most common problem is a blown cigarette lighter fuse. This occurs due to the circuit being overloaded. Many drivers connect powerful devices to the cigarette lighter: compressors, refrigerators, inverters. Even a standard cigarette lighter may not withstand prolonged operation of a powerful heater.
The second common problem is oxidation of contacts in the block under the hood. Moisture and temperature changes contribute to the formation of plaque on the fuses and relays. This leads to increased resistance and overheating. Cleaning your contacts regularly will prevent this problem.
Sometimes the relay fails. Unlike a fuse, a relay does not have a fuse link, but it does have a coil and contacts inside that can burn. The relay is checked by replacing it with a known good one or testing it with a multimeter.
- 🔌 Check that the battery terminals are securely connected
- 💧 Inspect the blocks for traces of moisture
- 🔥 Pay attention to the burning smell in the block area
- 📉 Check the voltage at the battery terminals
If you notice that fuses are blowing frequently and for no apparent reason, the problem may be with the generator. Excessive voltage in the on-board network can lead to failure of not only fuses, but also all electronics.
Before replacing a fuse, clean the contacts in the socket with a dry brush or compressed air to ensure reliable contact with the new element.
⚠️ Attention: If you smell something burning or see smoke after replacing the fuse, immediately disconnect the battery and call a tow truck.
Sometimes the problem lies not in the fuse itself, but in the wiring. Broken insulation, chafing of wires, or moisture getting into the connectors can cause a short circuit. In such cases, a complete wiring diagnosis will be required.
Prevention and maintenance of the electrical system
To avoid frequent fuse replacements, it is necessary to carry out regular maintenance on the electrical system. Inspect blocks for moisture, dirt and oxidation. If necessary, clean the contacts with special aerosols for electrical contacts.
Do not overload circuits with additional devices. If you are installing a powerful audio system, additional lights or an alarm system, be sure to connect them through separate fuses and relays, and not through standard circuits.
Monitor the condition of the battery. A weak battery or poor terminal connections can cause voltage surges that negatively affect fuses and relays. Regularly check the electrolyte density and voltage at the terminals.
Use only original fuses or high-quality analogues from well-known brands. Cheap Chinese counterfeits often have incorrect denominations or low-quality materials, which leads to their premature failure.
Regular inspection and cleaning of contacts in fuse boxes significantly reduces the risk of sudden failures of the vehicle's electrical equipment.
Don't forget to check the condition of the wiring under the hood. The insulation of the wires may rub against metal elements of the body or frame. Detected insulation damage must be repaired immediately to avoid short circuits.
If you are not confident in your abilities or cannot find the cause of the malfunction, it is better to turn to professionals. Poor electrical repairs can lead to serious consequences, including a vehicle fire.
